56 Configuring & Monitoring The Switch ELS100-24TX

Downloading Via TFTP

To perform a TFTP download, you must first configure the ELS100-24TX
switch. This consists of programming the switch with an IP addre ss, if this
has not already been done, and entering the IP address of the TFTP
server and the name of the upgrade file. To program the switch IP
address, go to the Syst em Configuration Men u which is accessible from
the Main Menu screen.
To download switch software via TFTP, do the following:
1. Select TFTP Server IP Address from the Download Software Menu.
2. Enter the TFTP server IP address and press [Enter].
3. Select TFTP File Name and enter the file name to be downloaded
from the TFTP server.
4. If necessary, configure the address of an IP gateway to reach the
server from the switch using t he Default Gateway f ield o n the Sys tem
Configuration Menu.
5. Configure the TFTP server by copying the download file from the
upgrade disk to an appropriate directory and starting the server.
6. Select Start TFTP Download and press [Enter].
To verify that the TFTP download has been successfully completed ,
note the software version level display ed o n the Ge neral Informat ion
Screen accessible from the Main Menu. This number should match
the version number that appears on the upgrade disk.
Configuring Spanning Tree Parameters
The ELS100-24TX switch supports the IEEE 802.1D Spanning Tree
Protocol. This protocol allows redundant connections to be created
between LAN segments for purposes of fault tolerance. Two or more
physical paths between different segments can be created through the
switch, with the Spanning Tree Protocol choosing a single path at any
given time and disabling all others.
For a TFTP download, the path to the file must be in-
cluded in its name. For example, if the upgrade file
name is filename.bin and it resides in the directry /
usr/tftp on the TFTP server, then you must enter the
TFTP file name as: “/usr/tftp/filename.bin”.
